Answer:
M+11=L
Step-by-step explanation:
- M= the weight of Marcia's dog.
- L equals the weight of Lisa's dog.
The weight of Marcia's dog plus 11 = the weight of Lisa's dog.
24+32+30+28=114
114÷2 groups =57
57 kids in each group
To make sure we don't have negatives under the square root, we specify that
(x is greater than or equal to 0). We'll use this fact later on
--------------------------------------------
Start with the given inequality
and square both sides to get
. Couple this with the fact that
means we have this compound inequality
What does this mean? It means that we can pick any value from 0 to 49 (including both endpoints) and it will be a solution to the inequality. This applies to the values
49, 48 and 44Answers: Choice C, Choice D, Choice E
Let's start with 17 seats and just bikes. That is 34 wheeles. Now, each bike we replace with a go-kart will add 2(because we take away 2 and add 4). We need to add 14 wheels. This means we will replace 7 bikes with go-karts. 7 go-karts (28 wheels) and 10 bikes (20 wheels) is the answer.
Quarters. 34×0.25= 8.50
dimes. 13×0.10= 1.30
Nickels. 4×0.05= 0.20
total=10.00
(21×0.25)+(9×0.10)+(4×0.05)+(4×0.10)+(13×0.25)=10
